Specification of Letters Patent.

Application file d December 13, 1912. Serial No. 736,597.

To all whom it may concern:

Be it known that I, ALFRED ERNST, a citizen of the United States,resident of Pittsburgh, in the county of Allegheny and State ofPennsylvania, have made a certain new and useful Invention inGasGleaners; and I declare the following to be a full, clear, and exactdescription of the same, such as will enable other skilled in the art towhich it appertains to make and use the invention, reference being hadto the. accompanying drawings, .and to letters or figures of referencemarked thereon,'which form a: part of this specification.

Figure 1 is a ,central vert'cal section of The invention relates toapparatus for cleaning gas, and particularly gas liberated in gasproducers from bituminous coal and it consists in the novelconstructionand .combinations of parts, as hereinafter set forth.

In the accompanying drawings, illustrating the invention in an apparatusof preferable form, the numeral 2, indicates a casing, the upper portion3, of which is preferably of cylindrical form, and is provided with acentral recess 4, the bottom of which is in the form of an annularwater'seal cup 5, around a central opening 6. To the top of this portionis attached the outlet pipe 7.

The chamber in this portion disposed around the recess 4 is annular, andis provided with perforated racks 8, for the reception of dryingmaterial designed to ab-- sorb inoist-ure from the gas after beingwashed. To .this upper portion is connected the main lower portion ofthe casing, extending downward and provided at its bottom with awater-holding connection 9,

which is preferably a water-seal tank or basin having am overflow pipeat 10. In the casing are provided an upper chamber 11, for a centrifugalwater distributing device, and a lower entrance chamber 12, whichextends below the water level and to which the entrance pipe orinlet-13,, is connected. The wall of a tubular throat or partitionpassage 14, extends centrally upward into the upper chamber 11, anddownward from theupper chamber through the lower chamber, separatesthese chambers and is'terminated at or slightly below theoverflow levelby a horizontal series of .s notches or passages 15, through which thecrude gas is designed to pass from theentrance chamber, into this throator passage and upward into the main cleansing chamher. A drain passage16, which may be circumferential, extends downward from the slopingfloor of the upper chamber into the water holding basin. This throat orPatented May 20, 1913.

partition passage is therefore designed to provide communication betweenthe en..

trance chamber and the washing chamber only through the water of thetank.

Through the central opening 6, of the top of the casing extends a shaft17, the upper portion of which is water-sealed in the cup 5,;above whichit is provided with a pul ley or other .means of communicating "motion.The lower end portion of the shaft extends into ,the interior verticaltubular passage 14, and is provided with blades 18. The middle portionof the shaft is provided with fan blades 19, and,'below these, with arotary inverted cup device, the skirt or wall of which extends downwardaround the upper part of the tubular passage l-it. This skirt or wall isprovided with exterior ledges 20, which may be and usually are ofbracket-form and horizontal or inclined;

and opposite this wall the casing wall is 1 provided with flanges 21,which are inclined. The casing flanges are arranged at levels betweenthe cup ledges, and, as the casing wall and cup wall are designed to beparallel, or nearly so, the annular deflecting passage between them isarranged to distribute the gas and water particles inan even manner.

A water supply is provided in the upper part of the casing, asindicatedby the jets at 22. shown in the chamber 12, near the water level andpreferably directed toward the passages or serrations 15, these beingdesigned to wash away the tar'and soot which tends to float andaccumulate in thewater of the entrance chamber-around these passages.

Inthe operation of the apparatus, the

crude gas from the producer, entering the lower chamber 12, is drawnover the surface of the water inward through the horizontal series ofnotchesor passages of'the tubular wall in separate streams, which aresubdivided by the bubbling action into small portions, which, beingbrought into contact with the mass of water of the tank, are ma-'terially cooled. Also much of the heavier soluble matter is taken fromthe gas. The gas, moving upward through the tubular passage 14, isdeflected downward by the skirt wall of the inverted cup, and, at thesame time, is given a whirling mot-ion, which continues as it passesaround the edge of this wall upward through the defleeting passagebetween the ledges of the cup wall and the flanges of the casing wall.Meeting the falling spray, which is given centrifugal motion as itpasses outward and inward between the flanges of the casing wall and theledges of the cup wall, it is further washed and cooled, the solublematters falling upon the sloping bottom of the upper chamber and beingdrained into the tank below through the circumferential drain passage ofthe casing. Below the drying chamber the wall and flanges of the casingslope downward, and the cup wall has also a downward slope, and theledges of the exterior of this wall are preferably arranged in staggeredrelation, or separated at intervals by vertical passages, it beingdesigned to obviate the collection of heavy extractive in this part ofthe apparatus, and to facilitate'its downward movement. The cleaned andmoistened gas is carried to the outlet through the drying material onthe racks of the drying chamber which is made sufliciently extensive toprovlde for a comparatively slow movement of the gas, and in this way topromote an effective drying action, so that the gas passing through theoutlet pipe will be in condition for use.

In some cases, in order to provide an abundant distribution of the wateror cleaning fluid, supply spouts 23 may be arranged around the casing atdifferent levels, to discharge the fluid toward or upon the shelves ofthe rotary inverted cup or deflector 25. In these cases, the casingledges maybe dispensed with, as the discharge from the spouts will causelateral inward currents of the gas.

I claim 1. Apparatus for cleaning gas, comprising a casing having anentrance chamber and a washing chamber, a water holder at the bottom ofsaid entrance chamber, an overflow -for said water holder, an inverteddeflecting cup within the washing chamber, and a tubular partitionpassage within the entrance chamber extending upward into saiddeflecting cup and downward into the water holder, said passage beingprovided with rotary blades above and passages at the water level forcausing the gas to bubble through the water from the entrance cham-- herinto the partition passage.
